1 Software Product Description PRODUCT NAME: HP Hierarchical Storage Management SPD PRODUCT DESCRIPTION HP Hierarchical Storage Management (HSM) for Open- VMS is a layered software product that extends the OpenVMS file system to allow efficient management of infrequently accessed (dormant) data. HSM migrates dormant data from online storage to less expensive nearline or offline (shelf) storage. The movement of dormant data to shelf storage is called shelving. The shelved data can be automatically and transparently returned to online storage when needed. HSM will also save valuable backup time, since the shelved data is already located on secure, removable media. HSM for OpenVMS Operation HSM operates in Basic or Plus Mode. Basic mode uses its own media manager and qualifies a limited number of device types. Plus mode allows the use of advanced storage devices. If used for remote tape devices, Plus Mode requires the Remote Device Facility (RDF) software. See the OPTIONAL SOFTWARE section for details. New and frequently accessed files remain online while older and less active files are automatically, or manually, shelved in accordance with user-defined policies. The directory information and file headers for shelved files are maintained on online storage devices while the data itself is on the shelf device. When access is needed to the shelved data, HSM automatically returns it to online storage. The file attributes may be viewed and modified without bringing the data back online. Control over the execution of the shelving process is either explicit or implicit. Explicit shelving is a process that has been started in response to a DCL command. The command can be issued directly to the OpenVMS Operating System or executed in an OpenVMS command procedure. Implicit shelving is a process that has been started by HSM in response to a trigger event or policy. The transparent management of HSM is set through HSM policies which: Specify which files are or are not to be shelved Set a high water mark on the online storage to automatically trigger shelving of dormant data Set a low water mark as a space recovered goal when your files are shelved Specify which processes should cause automatic unshelving HSM policies use predefined selection algorithms or scripts containing HSM-specific commands to shelve or unshelve files in response to trigger events. Trigger events are situations that, when set by an HSM policy, cause HSM to move files to shelf storage. Examples of specific trigger events are listed below: Volume occupancy full Disk quota exceeded High water mark reached Scheduled policy execution Trigger events, used in conjunction with appropriately designed selection criteria, free up enough online disk space to satisfy the policy goal.

2 The selection criteria include definitions that determine the appropriate files to be shelved in response to the need for shelving. Examples of selection criteria include: Least recently used and size combination Least recently used According to a user-defined script If you have a question about a particular device, contact customer support. ESL630e ESL712e - ESL9198DLX ESL712e ESL9198SL HSM for OpenVMS qualifies file access to shelved files on client systems where access is through DFS, NFS, or PATHWORKS. ESL9322S2 ESL9326D ESL9322L2 ESL9326DX Qualified Devices The following libraries and loaders have been tested by Storage Management Software Engineering. However, Storage Management Software Engineering does not test each of the devices with every possible combination of controllers and host systems. Because the HSM product and the Media Robot Utility (MRU) run in common environments, these combinations are tested first with MRU. Upon successful completion of the MRU tests, HSM is then tested in representative configurations. Note that MRU is not a prerequisite for HSM. Therefore, to determine if your specific configuration is supported, follow these steps: ESL9326SL ESL9595SL ESL9595S2 ESL9595L2 MSL5026DLX - MSL5026SL MSL5026S2 MSL6030L2 - SSL2020 STK ACS 1 TKZ6x TL891DLX 1. If you have a tape drive that is not software-defined as a jukebox (is not a library or a loader device), reference the OpenVMS Software Product Description (SPD xx) to determine if your tape drive is qualified for your platform and controller/adapter combination. 2. If your device is software-defined as a jukebox (it is a library or loader device), first check the following list to determine if it is supported by the media manager. If the device is listed, see the following instructions: a. Check the OpenVMS Software Product Description (SPD xx) to make sure the tape drive(s) in your library/loader are supported for your platform and controller/adapter combination. b. Check the MRU Software Product Description (SPD xx) to make sure your library/loader is listed by MRU for your specific controller/adapter combination. 3. Assuming your device is correctly connected and configured, it is supported by the common media manager.

SOFTWARE REQUIREMENTS OpenVMS VAX: OpenVMS Alpha: OpenVMS I64: V7.3 (SPD XX) V7.3-2 (SPD XX) V8.2 (SPD XX) V8.3 (SPD XX) V8.2 (SPD XX) V8.2-1 (SPD XX) V8.3 (SPD XX) Refer to the appropriate OpenVMS Operating System Software Product Description (SPD) for additional details. NOTE: Storage Management makes every effort to be as current or correct as possible in qualifying our layered products on the Operating System (OS) versions. The use of a particular OS by a customer can only be guaranteed by the customer s contract with OpenVMS or by a specific service contract. HSM Basic Mode does not require any software other than HSM and the OpenVMS Operating System. HSM Plus Mode requires a media manager. Incase HSM is used with Storage Library System (SLS), then HSM will use SLS itself as the media manager. 3

4 If HSM is used with Archive Backup System, ABS, then HSM will use the media manager installed by ABS as part of the ABS product installation. If HSM Plus Mode is not used with either SLS or ABS, then just install the MDMS V4.3 provided in the HSM V4.3. The media manager (MDMS) is still a manual install with HSM V4.3 as users may continue to use SLS/MDMS V2.9H in their environment. OpenVMS V7.2-2 and later versions provide support for Fibre Channel (FC) connected tape devices. This is accomplished through the use of Modular Data Router (MDR)connected to the FC Switch. MDR converts Fibre Channel protocol to SCSI protocol, which the tape device understands. HSM V4.3 supports this new feature in OpenVMS and later as used with MDR. See the SPDs referenced above for a complete listing of supported tape devices. Network Storage Router (NSR) M2402 by HP is a key component in a complete data protection solution. It allows multiple host servers to communicate with a SCSI tape device over a Fibre Channel link making backup speeds five times faster. HSM has been tested and qualified with Network Storage Router (NSR) M2402. The HSM V4.3 is compatible with the Multipath failover functionality on Tape devices as provided in OS OPTIONAL SOFTWARE SLS V2.9J or ABS V4.4, can be used in conjunction with HSM for an integrated Backup and HSM environment. SLS or ABS contains the Media, Device and Management Services software (MDMS). Remote access to tape devices in Plus Mode requires the Remote Device Facility (RDF). RDF requires a license and is available as a component of the media manager, MDMS, which is part of your HSM V4.3 kit. RDF V4.3I has been qualified for HSM V4.3. This capability is turned on through licensing of the following: Purchase of Storage Library System (SLS) Purchase of Archive Backup System (ABS) Purchase of an RDF license directly from Computer Associates International Inc. License Management Facility This layered product qualifies the OpenVMS License Management Facility. For more information on the OpenVMS License Management Facility, refer to the OpenVMS Operating System Software Product Description or the License Management Facility manual of the OpenVMS Operating System documentation set.
